I am upgrading the SSD in my Macbook from a SM128E to a 256gb Samsung 840. I wanted to use the SSD in my Macbook in my PC. I want to use RAID with the SM128E and another SSD, but I don't know which SSD to buy. I know the SM128E is made by Samsung and I want to get the drive that is basically the equivalent to the SM128E so I have an optimal RAID configuration.

I basically want to know which Samsung SSD was rebranded and put in Macbooks.
